Relay neurones, which are typically found in the central nervous system, often lack a myelin sheath because they are involved in processing and integrating information rather than transmitting signals over long distances. Myelin sheaths are primarily found on motor and sensory neurones, where rapid signal conduction is essential. The shorter axons of relay neurones allow for sufficient signal transmission speeds without the need for myelination, as their primary role is to connect and communicate with other neurones in close proximity.

What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
Where is the relay neurone in the reflex arc?
The relay neuron is located in the spinal cord in a reflex arc. It connects the sensory neuron to the motor neuron, allowing for the reflex response to be processed and carried out quickly without involving the brain.
Where are the cell bodies in relay neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
What is the correct route taken by an impulse after it haws a left relay neurone?
After passing through a left relay neuron, the impulse would travel to the right side of the brain to be processed in the cerebral cortex. The cerebral cortex is responsible for higher brain functions including sensory perception and motor control.
What is the job for the nucleus in a nerve cell?
The nucleus in a nerve cell contains the cell's genetic material (DNA) and controls the cell's activities by regulating gene expression. It is responsible for directing the synthesis of proteins essential for nerve cell function and maintenance.
What is a relay nerve cells?
Interneuron (relay neurone) Relays messages from sensory neurone to motor neurone. which make up the brain and spinal cord
What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
What do you call the neurone that connects the sensory and motor neurone together?
The neuron that connects the sensory and motor neurons together is called an interneuron. Interneurons facilitate communication between sensory and motor neurons within the central nervous system.
How does the passage of a touch signal pass from skin to the cerebral cortex?
Pressure receptors in the skin pick up the stimulus. It passes along a sensory neurone to the central nervous system. Within the CNS it is transferred to the cerebral contex via an association neurone, relay neurone.
What are the type of nerve cells?
There are three different types of neurone: sensory, relay and motor - which are involved in a reflex arc.
Where do neurotransmitters act?
They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone. There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.
Where is the relay neurone in the reflex arc?
The relay neuron is located in the spinal cord in a reflex arc. It connects the sensory neuron to the motor neuron, allowing for the reflex response to be processed and carried out quickly without involving the brain.
What is the path that nervous impulse takes through the nervous system?
A nervous impulse begins in the dendrites of a neuron, travels through the cell body and axon, and then is passed on to the next neuron via a synapse. This sequence repeats until the impulse reaches its destination, such as a muscle or gland, where it triggers a response.
Why doesnt your fuel pump kick on if the fuse and the relay are good?
It may be defective.
Where are the cell bodies in relay neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
How The Nervous System Functions In This Reflex Action?
Firstly your receptor cells pick up a stimuli and sends an electrical impulse along the sensory neurone's axon to the spinal cord.the impulse is then passed onto the relay neurons IN the CNS(the spinal cord decides what to do but the brain is also informed). The relay neurone then passes the command from the spinal cord in the form if an impulse to the motor neurone.the impulse travels along its axon to the effector. Hope it helps P.S. •relay neurones exist only within the CNS and not outside it. •reflex arcs take the shortest possible route
What is the correct route taken by an impulse after it haws a left relay neurone?
After passing through a left relay neuron, the impulse would travel to the right side of the brain to be processed in the cerebral cortex. The cerebral cortex is responsible for higher brain functions including sensory perception and motor control.
